Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"sediment means algorithm" » "sediment search algorithm" (Expand Search), "sediment gas algorithm" (Expand Search), "sediment edna algorithm" (Expand Search), "sediment metrics algorithm" (Expand Search)
"sediment based algorithm" » "sentiment based algorithm" (Expand Search), "sediment hosted algorithm" (Expand Search), "sediment water algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("element mapping algorithm") OR ((("sediment means algorithm") OR ("sediment based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mapping algorithm\") OR (((\"sediment means algorithm\") OR (\"sediment based algorithm\"))))".
• Removing quotes may allow a broader search: (( element mapping algorithm ) OR ((( sediment means algorithm ) OR ( sediment based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mapping algorithm") OR ((("sediment means algorithm") OR ("sediment based algorithm"))))*.
